I've been researching gaming PCs for a few months to upgrade from PS4, and I noticed there is a big emphasis on fps, usually aiming to get above 60fps. Most of the games I've played on PS4 are 30fps, although maybe a few are 60fps. They all feel super-smooth, and I've never thought I needed higher fps. I also watch a lot of YouTube in 30fps, occasionally 60fps, and it also looks very smooth.
Maybe this is based on experience, but would you think 60fps is high enough for most games, or do you think you notice a big difference above 60fps?
If you never played at 120hz+ you have very limited idea or benchmark to base what smooth is.
